Carew has now been sent back to the Serie A giants, where he is currently on-loan from Valencia, after reportedly punching Riise following a training ground spat.
National team manager Nils Johan Semb has admitted that the giant striker's behaviour was unacceptable, but 22-year-old Riise has made it clear that the feud is now at an end.
Riise said: "He (Carew) has apologised for what he did and I apologised for what I did. We shook hands afterwards."
